## Description
My older sister, Satsuki, is kind, caring, and soothing, and is the embodiment of the ideal older sister. My cute younger sister, Kae, is energetic and tomboyish, and she is attached to me, following me everywhere. I spent happy days surrounded by the two of them and our parents.

... However, there was a secret that only I didn't know about. Satsuki and Kae are the children from my father's remarriage, and are not related to me by blood...

Ever since I found out about this, the sisters have been making advances on me nonstop!? They want to distort my sexual preferences! And so that's the start of my sex life...
